    What Is the Acceleration in a Frictionless Pulley System with Varying Masses?

    Homework Statement Assuming ideal frictionless conditions what is the acceleration of the system if (a)m1=.25kg, m2=.50kg, and m3=.25kg and (b)m1=.35kg, m2=.15kg, and m3=.50kg. This is a picture of a table with m3 on the table, m1 and m2 hanging on the sides. Homework Equations a=Fnet/m...

    Box-Spring Collision: How Much Compression?

    Homework Statement 1.5kg box sliding on frictionless surface with a speed of 12m/s approaches a horizontal spring. The spring has a k of 2000N/m. How far will the spring be compressed in stopping the box? How far will the spring be compresses when the box's speed is reduced to half its initial...

    Straight Line Distance from D to A: Calculating with Pythagorean Theorem

    Well, I have not had a math course in about 15 years and this is my first time taking physics. The text that I have for my class is not that good as far as showing examples of how to do things. I drew the diagram and it has 3 given sides, then to find the distance it would be a 4th side, so how...

    Straight Line Distance from D to A: Calculating with Pythagorean Theorem

    Homework Statement Vehicle drives from a to b (south 100mi), then from b to c (east 200mi), then from c to d (north 300mi). What is the straight line distance from d to a? Homework Equations Not sure. Maybe Pythagorean theorem. The Attempt at a Solution No idea really. I drew a...
